In humans, brown eyes are generally dominant over blue eyes. Find the phenotypic and genotypic ratios of a cross between two heterozygous brown-eyed people. Choose This is a required question​

Answers

Answer:

Brown eyed genotype: Aa (eterofzygous) or AA (homofzygous)

The genotypes derived from the cross are: AA, Aa, Aa, aa

The phenotypes are: 3 with brown eyes and 1 with blue eyes (aa)

The phenotypic ratio is 3:1 (brown eyes: blue eyes) and the genotypic ratio is 1:2:1 (dominant homozygous: heterozygous: recessive homozygous).

What happens in a heterozygous cross?

In humans, the allele for brown eyes (B) is dominant over the allele for blue eyes (b). Heterozygous individuals, who carry one copy of each allele (Bb), will have brown eyes.

When two heterozygous brown-eyed individuals (Bb) cross, the possible genotypes of their offspring are:

BB (brown eyes): 25% chance (homozygous dominant)

Bb (brown eyes): 50% chance (heterozygous)

bb (blue eyes): 25% chance (homozygous recessive)

So, the genotypic ratio of the offspring is 1:2:1 (BB:Bb:bb).

As for the phenotype, the only possible one is brown eyes and it occurs in 75% of the offspring (25% BB + 50% Bb)

Therefore, the phenotypic ratio of the offspring is 3:1 (brown eyes: blue eyes)

It's worth noting that while this is the typical outcome of crosses involving the eye color genes, it's not universally accurate, as other factors and genes might have an influence on the phenotype. Additionally, in reality, eye color is a complex trait and many other genes are involved not just B and b, so the dominance is not always that clear.

O'protects the cell from intruders
stores the DNA

Answers

Answer:

The core controls and controls the exercises of the cell (e.g., development and digestion system) and carries the qualities, structures that contain the innate data.

Atomic pores, little channels that span the atomic envelope, let substances enter and exit the core. Each pore is lined by a set of proteins, called the atomic pore complex, that control what atoms can go in or out.

The core is spheroid in shape and isolated from the cytoplasm by a layer called the atomic envelope. The atomic envelope confines and ensures a cell's DNA from different atoms that seem incidentally harm its structure or meddled with its handling.

What are four conditionsrequired for fossilizationof an organism?

Answers

Answer:

The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils.
